Look at the divisions between 2 and 4. What level of precision does this stopwatch have based on the divisions marked on its face?

Respuesta :

Answer:  The answer to the top one is 5.3 s and the bottom one is tenths of seconds

Explanation: Hope this helps plz mark!! Thx

The average reading time obtained by using the stopwatch was 4.35 ± 0.56 seconds. The computer on the other hand delivered 4.43 ± 0.58 seconds.

Accuracy of the Stopwatch and Human Error

Human Errors arise from the fact that manual stopwatches have starting and stopping actions.

It is to be noted that this error although it is estimated to be up to o.10 seconds can be sufficient to change the winner of races where there is a close tie.

The precision of the Division marked on the face of the stopwatch

Another source of error is the degree of precision afforded by the digital stopwatch versus the manual stopwatch.

The digital stopwatch has two digits more than the seconds than is found in the manual stopwatch. This means that is subdivides time into the hundredths of a second. This makes it more reliable than the manual stopwatch.
